What is Polyurethane?

Polyurethanes are a group of organic polymers that are normally grouped with rubber. Polyurethanes are elastomers which are stretchy materials. They come from the reaction of diisocyanates, long chain polyols and short chain extenders. This process has proven itself to be a flexible method of producing customised elastomers with adjustable properties.

Polyurethanes achieve hardnesses on a wider range than any other elastomer and exhibit outstanding physical properties such as: abrasion, by far better than steel; tear resistance, superior to these of many other elastomers; resilience; load bearing capabilities. Through the years, their special properties made them indispensable in more and more fields replacing other materials with lower properties.

- Our polyurethane can be tuned to produce polymers of different hardnesses and physical properties to suit the application

- Our polyurethane is elastic and can absorb an enormous amount of trauma without permanently deforming (unlike UHMW and Delrin)
